Given an iOS app with a watch app and the watch app has bitcode explicitly enabled with
When a swift package is used in the watch target, building the iOS app against a simulator gives the following bitwcode warning in the
Built target SampleWatchApp Extension: Link SampleWatchApp Extension (arm64) step. (Building against a physical device does not lead to this warning.)
ld: warning: all bitcode will be dropped because '/Users/username/Library/Developer/Xcode/DerivedData/SampleApp-egrqmpcsrjdhaxfjdiwqjeljghpq/Build/Products/Debug-watchsimulator/LocalSwiftPackage.o' was built without bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target.
This does not make sense to me because AFAIK Swift Packages have bitcode enabled by default.
I created a simple sample project which shows this issue. There the local swift Package only contains the default "Hello World" code, so I do not see where there could be an issue.
- Do Swift packages not support bitcode for watchOS simulators or am I missing something else?
- How can this warning be resolved?
- Or is this a bug in the context of Swift Packages and bitcode in watchOS targets?
